Today we got our 3d printed nose cones… Our groups was a fail. It was all my fault since I didn’t look at the measurements of the cone in the program. I am very guilty. The nosecone was supposed to be 3-2 inches.
Look at this monstrosity:
I learned that successful people fail a lot of times to get to the top. Now the measurements are okay and a classmate is printing it for me.
Today we learned to used tools to practice when we measure how far/high our rockets go. The tools that we used are called a Clinometer, for height, and a Trundle Wheel for length. The clinometer measures heights when you point it up and release the trigger, then the gravity pulls the arrow down, making the arrow point at the exact angle marked below. But it differs the angle on how far away from the thing you’re measuring. There’s an illusion, where when you back away from something, it seems to get smaller, then you point the tool lower, and it is not as high. For example, at 17 ft away from a flagpole, it is 40 degrees, but at 10 ft, it is 80 degrees.
The modern trundle wheel is pretty simple when you roll the circle at the end of the stick, it clicks every time you reach a meter. The old ones you have to look at the measurements on the face of the circle and stop every time you reach a meter.
Today we made our rockets! First, we cut out cardboard wings and measured them. Next, we wrapped them in duct tape that was very colorful. We used sandpaper to roughen up the bottles so it would be easier to glue on the wings. I had a chopstick for a needle and I sanded nice and clean. We have our 3d design for our nosecone and it will be awesome!
This year we have done rocketry! When my teacher first said it, I was very optimistic about it. Then we got shuffled and put in groups. We named our group J.E.X.L after the first letter in each of our names. We thought that it would be a sort of N.A.S.A. sort of thing. Then for homework, we had to bring in ideas and pictures for the inspiration board. It was really fun when we printed out pictures of different rockets and rocket launches. Also for homework, we got to study Isaac Newton and his laws of motion to help us better understand the physics behind the rockets. Then we glued and designed our Inspiration Boards. It looked nice with the frilly cuts and the different colors. But the important part was that it inspired us on what to do when building and launching. Now, we are bringing in materials to build them and I am in charge of cardboard. It will be so fun to launch!
